Be itknowu that LCHAnLns S. Dona-of Chicago,

in the county 'of (look, and State of Illinois, have invented a new anduseful Appin'atus ior Un loading Grain from'Wagons; and I doherebydeclare and make known that the following is a full, clear` andexact description of the same, reference being had to the accompanyingdrawings, and'fthe letters and' figuresma-rked thereon,

whiehfonn part of this specification.

'My said'invention is mainly designed for use in uu-v loading ears of fcorn, potatoes, and such grain as is brought in in wagons orslei hs Ainbulk; and

' It consists in .having a pla formscpnstructed in any suitableposition, vand on ahi'gher leveLthan the ,'re -ceptacle into which thecorn or other produce fis tebel ,i dscharged'i'rom the wagon, saidplattbrrn bcingpxofl ifded with a' mpvable trap, upon whielreithertheentire wagon or sleigh, or 'only the rear *wheelsfof the wagon may bedriven and placed,so that by depressing the said \movablevtrap, in thelatter case, or causing it toassume aposition inclining downwards towardthe the rear end-board, can be readily precipitated into the appropriatereceptacle or bin, whence itmay be elerated and distributed at pleasure,as hereinafterl more fully described.

To enable those skilled in the art to understand howto construct and nsemy saidinvention, I will proceed to'describe the 'saine withparticular-ity, making reference in so doing .to the aforesaid drawings,iu which- Y Figure l represents a side elevation of 'my invention;

ignre 2 isa vertical section, showing the saine in position for.discharging the grain;

Figure 3 is a bottom plan view ofthe platform and y.

. which the giain or produce is to' be unloaded.

VB represents a movable' trap, of suitable size .and

form, large enough to receive a wagon which is sus` pended upon anaxleor shaft', 0, passing acrossand beneath it, a. little to'one side ofthecentre, longitudi- "nallyto which trap said axle is 'firinljyr securedby the metalic straps C Q ',as shown in the drawings;

The ends ofsaid shafts C formrjournals or trnnnionsf,

upon whichsaid trap mayturn or tip, as indicated in iig?, said journalsbeing supported in suitable boxes or hearings A', as shown in thedrawings.

'rear,'t he contents of the 'wagon or' sleigh, by raising `lwheelsthereto Q in fig. 2. i

- The said trap B fits neatly into an opening iliade to i 'ive igin theplatform A, which opening -rnay he 4unt-il'the trap is brought to theposition shown I lined or faced with metal, as seen at n', desired, to'preventits being wennl bythe. movement of the trap,

Kat each end of which supports are projected from the opening to receivethctrap, andsustainthe same.

lhe support a' is stationary, but thefsupport Ll) is secured to theunder side of the 'platform byj-slotted supports, or by supports.passing'through slots. in thel bar, to admit of a sliding movelneiit'tosaid-bar or support, so that it n'lay be withdrawn from underfthe end ofthe trap when it is desired to tip 'the-platform.

l 'The levels E 14 Gjfare'connected,as'sliown, with said bar D, so thattheoperator, by moving thelever G,.`

can withdrawor replace-,the support I), with reference' to the trap 13,as desired.A

At the point beneath vthe end of the said trap, where the catch Dslides, a-plat e, b,` is' attached tothe trap, to prevent tlie wearingofthe trap byj the friction.

Below the rear end of the trap the bin S is loe'ated, or said bin maybelocated at a distance, and the grain.' 'may b'c' discharged 'into achute, which conducts it to the bin.

Upon a floor or frame beneath the platter-n1 A or the tiap'B, parallelwith and under the shaft O, is a shaft, L, supported in suitablebeni-ings, as showin-said shaft being provided-with a drum, M, and also,upon one end, with a bevelled gear-wlieel, K, which latter engageswitbthe bevelled pinion J, upon the vertical shaft H,

l which .passes up through the platlbrm A, andis pro` vided with awheel, I, as shown, whereby said shaftsl and L can be Arevolved bytheoperator standing upon the plattbrin A.

To the said drum Mis attached one end of a cord or chain, R, theopposite'eudof said cord or chain .beingattached to a point at c, nearthe forward en d of the trap B, as shown. l i

A second cord or chain, Eli-.is valso attached vto said drum M, passingin the opposite direction, to be attached at tl to a point ueartherearend of said trap B, both of said cords passing respectively underpulleys or sheaves e j, as shown, and being of such length that when onecommences to wind upon said drum, by the revolving thereof, the otherimmediately unwinds.

In describing the operation of the above-spceied apparatus, wc willassume the trap .to be in' a horizontal position, forming part ofrtlreplatform, supported at eaeh end bythe projection e' and the slidingbarD.

The wagon containing the ears otVcorn, potatoes, or other produce inbulxk, yist'hcn driveu upon said trap, and properlyl secured thereto byclamping the fore by any suitable incans,.a s indicated at The rearenddaonrd, X, is then'raised-np, as indicated in said iig. 2, andthe-cartelli) withdrawn from beneath thcrear end ofthe trap, by movingthe lever G back, when vthe operator turns the wheel I, on the shaft H,in that direction, which will windthe cord l upon the drinn M, andunwind the cordv lt thereli'ozn.

stored to its originel position, and the catch D moved under it 'enrend,"when the. wagon is relenscthnnd moves oil' to giverplnee toanother, when the operation ls repeated;

It will he. observed that the oscillating tmp B pirot/ed :it one side ofthe eentml line between .the cnds,'

so that while the weight ot the wagon is nearly lui-lanced upon thesnpports'A' A', there isrnfprelmnder- :mee behind, so to facilitate thedescent of thereonv end ofthe tmp, making it necessary to 'have but :tslight power or torce to opemto thenppamtus, either in lowering orraising the tmp.

If desired, zrhmke lusty he applied to the slmtt L- to prevent the toompid desmnt of the trap, in case the diste-nce from the centre'of' thetrap to the supportingpoint-s should render the prepondernnce of theweight` at the rear 'end o t thc trnpz'so grent ns to .ezmse n too11i-pid precipitation of the trop without the. applicntiml` of a. hrnke.

han'ingjhe tmp suplmrted :ttor 'nbontnlidwny from lemh end bringto-emthle'-thc nppnmtus to he opera-ted with ver) little power-or byhand.

, lt 'mitikie ohsewi-d, furthermore, that when it is de sited tomilozul,lo; sini ply placingy the rear end or wheels .of the wagon upei'tlietmp, len-ving the forward wheels resting upon the stationery platform,the said trapmay asm A be so suspended or supported as to have aperpendicular descentand ascent in a. horizontal position, s the rearend of the wagon would thereby be lowered so as to cause the contents ofthe wagon to discharge, as above `Specified. .l n such esse, anysuitable mechsnil means may be employed for suspending or sustainingsaid tmp,

` and lbrimlnn'ting to it the requisitev motions, in voperating thea-ppnmtus, to discharge or unload trgt-53nd restore the someto theiroriginal position they :tre unlozuled,ns afomsaid.

When the tmpis constructed :ind arranged so ssto I move vertically, ltis obvious that the stop a must be constructed so as to more back whendesired, the same -ns lthe slide D.

Hering described the nnture,'constmction, und op eration of rnyinvention, I will now specify what I claim as new, and desire to secureby Letters Patent.

1. I claim, in eombinntion with a plntfonn, A, and. n movable tmp,1%,otnnnt-ing as described, a. stationaryl or'lnovnble-stop,a, and nslide, D, an"u` tially :is and for the purposes specified. 2. l claim;in combination with the pivoted trap B, Vn drum, M', and .cords'B 1,:munged tooperntc in the mannersetforth and specified. 7

.3L I claim the combination of thc swinging trap IB,
